The basic working principle of the utility model is as follows:
the oil gas volatilized from the normal pressure storage tank 1 enters an oil gas condenser 3, about 95 percent of the oil gas is condensed and then changed into a liquid phase from a gas phase, and the oil gas enters a recovery oil tank 4 to be reused as an oil product; the residual 5% volatile oil gas which can not be recovered is pressurized by a booster pump 8 and then is led into an air inlet pipeline 10 of the heating furnace, and is mixed with air and enters a heating furnace 15 to participate in combustion, so that the volatile oil gas is reused as fuel gas and releases heat. In order to prevent the content of volatile oil gas in the heating furnace air inlet pipeline 10 from reaching the explosion limit, the concentration of the volatile oil gas in the heating furnace air inlet pipeline 10 is monitored in real time by installing the combustible gas online analyzer 14. When reaching the preset oil gas concentration high value point, the combustible gas on-line analyzer 14 immediately sends out a high value signal, and the first fast-switching valve 9 and the second fast-switching valve 12 immediately act after receiving the signal: the first quick-cutting valve 9 is closed, the volatile oil gas is cut off to continuously enter a channel of the heating furnace air inlet pipeline 10, and the volatile oil gas is quickly diluted by air continuously supplemented into the heating furnace air inlet pipeline 10 and is far away from the explosion limit; meanwhile, the second quick-switching valve 12 is opened to quickly vent the volatile oil gas, so that the safe operation of the heating furnace 15 is ensured. When reaching the preset oil gas concentration low value point, the combustible gas on-line analyzer 14 immediately sends a low value signal, and the first fast-switching valve 9 and the second fast-switching valve 12 immediately act after receiving the signal: closing the second quick-cutting valve 12 and stopping the volatile oil gas from emptying; meanwhile, the first quick-switching valve 9 is opened, and the volatilized oil gas continues to enter the air inlet pipeline 10 of the heating furnace to participate in combustion.
